Suicide is a very serious matter; it cannot be undone. If you're feeling suicidal, you need to talk to someone. Even if there is no one in real life, there are thousands of teenagers who feel the same way and can talk you out of it. Or, if you would rather talk to an adult, there's /r/suicidewatch. Suicide is never the best solution. Remember that you are loved, always.
